Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2025-67230 is a high-severity Incorrect Default Permissions (CWE-276) vulnerability in Todesktop Builder. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Services File Permissions Weakness (T1574.010); ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-67230 is an improper permissions vulnerability (CWE-276) affecting the handler for the Custom URL Scheme in ToDesktop Builder version 0.33.0. Published on 2026-01-23, it carries a CVSS v3.1 base score of 7.1 (AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H). The issue stems from insufficient validation, enabling attackers with renderer-context access to invoke external protocol handlers.
Exploitation requires low privileges (PR:L) and renderer-context access, occurring over the network (AV:N) but demanding high attack complexity (AC:H) and user interaction (UI:R). Successful attacks can achieve high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U).
Mitigation guidance appears in ToDesktop's security advisory TDSA-2025-002 at https://www.todesktop.com/security/advisories/TDSA-2025-002 and changelog at https://www.todesktop.com/changelog.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.
Requires least-privilege defaults so that installed files are not world-writable by default.
Requires documented, restrictive configuration settings that cover file and directory permissions.
Enforces access restrictions on changes, including permission settings applied during installation or configuration.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Hardened baselines and configuration management explicitly require correct default file permissions.
Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.
Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.
Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
